I too have had swollen lymph nodes under one arm prior to my periods for many years and they would go way as soon as my period arrived. I pretty much learned to live with them. However the situation got worse and then the OTHER underarm nodes became swollen and never went down.
I started on Dr Schulze's protocols: First doing the De-Tox tincture about 5x per day with water. I noticed the nodes going down within a few days. However not completely. Then I added lymphatic massage and that helped immensely. Then I did his Liver and Gall Bladder cleanse for 5 days and that helped even more.
Now my nodes are gone for the most part and when they act up I just start massaging them and detoxing.
I am sure this will help you. I never suffered from migraines however. My other doctors were unable to help me as much as Dr Schulze did.
